UNITED STATES PATENT OFFICE.

JOHN LEWIS TANDY, OF KANSAS CITY, MISSOURI.

Tor on Application filed June 25,

To all whom it may concern Be it known that I, J 012m LEWIS TANDY, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Tops or Covers, of which the following is a specification.

The invention: relates to improvements in tops, or covers, of the type adapted to reduce temperature by the evaporation of moisture; and the object of the improvement is, to provide an inexpensive, and effective, removable top or cover for various receptacles, such as jars, JilllS, baskets, and numerous other portable receptacles where their contents are desired to be kept cool and fresh, or under the protection of a cover, to exclude dirt and the many forms of animal life, to prevent certain kinds of contents from splashing out, or spilling out, while the receptacle is being ported about; and to provide a top or cover properly adapted to be applied to receptacles equipped with my improvement in cooling devices, (as mentioned in the specification for same, in my application for United States patent, allowed February 5, 1923), referred to hereinafter.

Referring to the accompanying drawing illustrating the improved top or cover, as adapted to be applied in some of its various forms;

Figure 1 is a perspective view illustrating a pail with the improved top or cover applied over its top portion;

Figure 2 is a perspective view illustrating the improved top or cover in a modified form applied to a basket; Figure 3 is a sectional view of the cover applied over an ordinary receptacle in connection with the said cooling device;

Figure l is another sectional view of the cover applied over an ordinary metal top on a receptacle;

Figure 5 is a detail sectional View showing a portion of the improved top or cover in a modified form of water containing chamber: otherwise it is a sectional view of Figure 1.

Referring to the drawing, the body portion 1 of the improved top or cover, comprises a sheet of fabric material of suitable texture to absorb moisture, such as canvas or the like, cut and made up to conform to the shape and size of the opening of the receptacle, over which it is to be applied, as

COVER.

turn down over the outer edges of the opening of the receptacle 3, the valance 4 is thus formed, as illustrated in the drawing, engag ing around and underneath the outer rim of the opening of the receptacle 3. lVhen the string 2 is drawn and tied fast around receptacle 3, the valance 4- may be pressed downward with the hands, stretching the cover over the opening, with the result of a closure scarcely approached by metal or wood covers.

Then the contents of the receptacle are further protected by a steady supply of moisture to the fabric, of which the cover is composed, as the moisture closes the pores of the fabric; and the constant evaporation lowers the temperature within the receptacle. Hence the improved top or cover is provided with a water receptacle or chamber, which I have found it convenient to form as an oval shaped roll 5 extending around some portion of the fabric composing the body 1, preferably as shown in Figures 1 and 2 of the drawing. The water chamber 5 may be formed in any manner preferred, as by stitching an extra piece of the fabric material to the body 1, which is a practical way of forming the required chamber 5 shown in the figures of the drawing. At some point along the water chamber 5 the opening 6 is provided for the intake of water as often as required, and it is closed by the use of any of the ordinary stoppers, as the removable cap 7.

Figure 2 of the drawing illustrates the improved top or cover as applied over the opening of a different kind of receptacle, a market or picnic basket. It also illustrates the cover provided with a modified form of the water chamber 5; or the extension of branches from the said water chamber 5, indicated by the reference number 15 in the Figure 2. The improved top or cover is adapted for use, not only on the smaller receptacles, but also on receptacles of larger size, as for instance, a shipping crate for fruit and produce; and for the lighter Weight produce, such as lettuce and the like, a crate of considerable size can be handled easily; and for receptacles of the larger size, the top or cover for same must be enlarged proportionally, consequently there is a larger fabric surface to be supplied by moisture from the water chamber 5, hence I have provided branch water chambers .extending from the water chamber 5.011 the body 1, shown in Figure 2, as a preferred means to facilitate the distribution of water to supply moisturefor the entire fabric surface of covers of the larger type. The intake 6 may be stationed on either, or both, of the chambers, 5 and 15, as preferred.

Figure 8 of the drawing illustrates the improved top or cover applied to a cylindrical receptacle in connection with said cooling device indicated in the drawing by the reference number 8, and applied around the receptacle 3. The body 1 is applied over the top of the receptacle 3, and is secured thereto by means of the string 2 drawing fast the valance portion l, engaging underneath the top portion 8 of the cooling device 8, as shown in the drawing. It is obvious that the best results obtain when the receptacle is surrounded and covered by fabric material supplied with moisture for tie evaporating and cooling process, and this result is obimproved top or cover over the ordinary metal top covering of a receptacle, to obtain the cooling effect within the receptacle. Figure 4 illustrates the improved top or cover applied to the receptacle 3 in the usual manner, but resting upon the metal top 9.

I have illustrated in Figure 5 of the drawing a modified form of construction for the water chamber 5, in which a tubular member 10 of suitable material (such as a heavier or stiffer fabric, rubber, or sheet n'ietal) provided with a series of perforations 10*, is inserted within the enclosure 5, thus supplying reinforcement, or amore rigid construction of the cover, which enhances its usefulness in some conditions of its various applications. It is obvious that the operation is substantially the same as the other form of construction shown. The water pereolates outward through the perforations 10 and is absorbed by the fabric material of the cover, as with the other form of construction shown.

It will be seen, that I have thus provided a simple, inexpensive, removable and portable, top or cover, for portable receptacles,

embodyin the essentials of a cooling proc ess by evaporation, when applied: that functions. whether the receptacle is sitting still. or is iostled about by themotion of a vehicle or common carrier; that can be cleansed by scalding, andkept in asanitary condition.

I have thus illi'istrated and described my invention in a preferred form, yet I desire the right to make suchchanges as may fall within thescope of the claims.

I claim:

1. A removable top or cover for receptacles, -con'1prising a covering composed of fabric material, a part of the fabric material composing said coveringbeing formed as a water chamber adapted to receive a supply of waterand feed the same gradually to the remainder of said material.

2. A removable top or cover for receptacles, comprising a covering composed of fabric material, a part of the fabric material composing said covering being formed as a closed water chamberadapted to receive a supply of water and feed the same gradually to the remainder of said material, anda draw string threadedthrough the margin of said covering for securing the same to the top of the receptacle.

3. A removable top or cover for receptacles, comprising a covering contiposed of fabric material, a part of the fabric material composing said covering being formed as a closed water chamber, with closed branch water chambers projecting therefrom, adapted toreceive a supply of water and feed the same gradually to the remainder of said material.

at. A removable top or cover for receptacles, comprising a covering composed of fabric material, a part of the fabric material composin said covering being formed as a closed water chamber, and means of reinforcement within the said closed water chamber adapted to receive a supply of water and feed the same gradually to the remainder of said material.
